When I was about 7 I had one and decided the little one was the baby poo, the middle one the mummy poo, etc., and then I got sent to my room just as they were about to announce the name of the new labrador puppy on Blue Peter. I had to wait until the following week to find out and it was Buttons - silly bloody name - I had written in with something far more interesting but I can't remember what it was.

I could tell you a story about an alcoholic ex boyfriend, a massive turd, a washing machine powder drawer and an irate, very hungover resident landlord (and the miss use of my tape measure to calculate whose arse had sufficient clearance to perform the deed) but I'd totally be outing myself.

Could an outside door or largish window have been left open OP? If the cats had poo'd in the room before another animal (badger/stray dog tec) had got into the house they may have poo'd there too out of territory marking?

It all sounds a bit like the dark dark night when the big skeleton and the little skeleton and the dog skeleton went on a walk through the town and found the zoo with all sorts of other skeletons to me.
